Re: East Texas?
There is a range in Panola County (Carthage). I used to live pretty much right next to it when I lived with my parents. I still shoot there when I go there for whatever reason. It's only 45 minutes from me now. The range is OK, nothing fancy. It has covered areas for pistol, rifle (25, 100, 200yds), and for NRA (200, 300, 400?, 600yds).
There is a range in Lufkin, which is about 20 minutes from me. I haven't been there or applied for a membership yet. From the pictures I have seen, it looks decent.
There is also a range near the Shreveport/Bosier City, LA area that looks really good. Has a range that goes out to 1000 yds. It also has steel target set ups. I haven't been to this range either, but I may in the future.
